This robot moves between the two parallel white lines on a black surface.

The robot uses 2 TCRT5000 sensors in order to detect the white lines.

It has two 6 V geared DC motors, two wheels and a caster ball wheel.

The robot was powered by a 9 V alkaline battery.

PIC16F628A was used as microcontroller for the robot.

L293D motor driver was used for the driving of the DC motors.

Motors were driven by differential drive system.
